Abstract
A bandpass radome is described including inductive layers comprising periodic conductive grids. First and second capacitive patch layers may be disposed above, and third and fourth capacitive patch layers may be disposed below the inductive layer to realize a 2-pole bandpass radome. An additional inductive layer and a fifth and sixth capacitive patch layers may be added below the fourth capacitive layer to realize a 3-pole bandpass radome. Conductive posts may connect one of the uppermost patch layers to one of the lowermost patch layers without connecting to the intervening inductive conductive grids. The conductive posts may form a rodded medium to suppress transverse magnetic (TM) surface waves. The total thickness of the bandpass radome may be less than 1/30 of a free-space wavelength at the center of a passband frequency. More than one passband may be separated by a ratio of center frequencies exceeding 1.5.
